An internet-connected doorbell isn't a new idea. The Doorbot of a few years ago was clunky and ugly, but tantalizing: someone rings your doorbell, your smartphone blurts and buzzes, and with a tap, you can initiate a videochat with the visitor. It doesn't matter if you're in the kitchen, at the office, or on Oahu. You can talk to them and see them. They can hear you, but they can't see you. If it's a delivery, you can give the guy permission to leave a package and instructions on where to stash it.
The Ring Video Doorbell offers a more refined and comprehensive approach. It adds motion sensing, so it can alert your phone when somebody walks through your yard or onto your porch. It also records video and audio of each event (a ringing of the bell or a motion detection) and stores it in the cloud for later review.
The Ring unit costs $200, and you install it yourself. It's about the size of a Cracker Jack box, with a 180-degree HD camera near the top. Below the camera eye is a circular button surrounded by an LED ring. At the bottom is a speaker for barking commands at your friendly FedEx driver. The companion app is free, as is the user account that lets you access the Ring's features. The cloud storage of all your recorded events is free through April 1, and then $3 per month or $30 per year.
The Ring Video Doorbell doesn't offer a live video feed or the ability to constantly record footage, but Ring does say it will allow remote camera access at some point in the future, so you can take a peek even when nothing triggers the camera.
All the tools necessary for installation are included—even caulk and a miniature level. Before you mount the Ring, you charge it using USB (you'll probably have to take it down and recharge it once per year) and connect it to your Wi-Fi network, which happens through the smartphone app.
I couldn't install it where I wanted to—my boring old doorbell sits in the middle of a piece of molding far too narrow for properly mounting the Ring. After viewing the video feed from various locations, I chose a spot on the side of my house near the door. Had I been able to install the Ring where my old-school doorbell was, I could have used the existing wiring to power it, and the chime already installed in my house. Such a hardwired installation would eliminate the biggest disadvantage of going completely wireless: You must have your phone nearby in order to receive an alert of someone at the door. Additionally, a babysitter, housesitter or the like would have no clue when someone is at the door unless you take the time to add them as an approved user on your Ring (this also requires them to have a smartphone running the app).
